CROSS-REFERENCES TO RELATED APPLICATIONS

This application is related to and claims priority from commonly owned U.S. Provisional Patent Application Ser. No. 62/771,205, entitled: Dynamic Verification Method and System for Card Transactions, filed on Nov. 26, 2018, the disclosure of which is incorporated by reference in its entirety herein.

TECHNICAL FIELD

The present invention is directed to secure card transactions.

BACKGROUND OF THE INVENTION

Traditionally on a card, such as a credit card 10, as shown in FIGS. 1A (front side 10 a) and 1B (rear side 10 b), the CVV (Card Verification Value)/CVC (Card Verification Code) is a three digit code 15. The CVV/CVC is printed on the rear side 10 a of the card 10, and is typically used in online transactions. Typically a card issuing processor verifies the CVV against the Primary Account Number (PAN) 14, a 16 digit number typically embossed into the card 10, best viewable on the front side 10 a, for example, in FIG. 1A, the PAN 14 is 5412 3456 7890 1234 (with the first four to six numbers being a Bank Identification Number (BIN), for example, for the card 10, the BIN is 5412). The expiration date of the card is typically printed on the front side 10 a of the card 10, for example 12-05 meaning December of 2005.

Traditionally the card transaction verification at the card issuing processor involves a balance (or credit limit) check, expiry check, CVV match against card number, and any additional fraud rules. Card data can be compromised for a variety of reasons at the user side (such as by key loggers or phishing), data breaches at issuer, acquirer or merchant, or simply susceptible to brute force attempts.

To protect against such compromises, card schemes have developed strong authentication/3D secure, which typically involves an additional step in approving card transactions, which are typically implemented, such additional static password, known to the user, or a dynamic one-time password is sent to the registered phone number. Some regulators in specific countries recommend/mandate the use of strong authentication, often based on transaction type/value thresholds. Typically this strong authentication is carried out by an Access Control Service (ACS) module, which is implemented by a provider (ACS provider). This ACS provider is integrated into the card issuer processor and facilitates the additional authentication for the card transactions.

In order to secure card transactions, when the card is not present, some cards now include a dynamic CVV. With this dynamic CVV, a chip display on the rear side or back of the card changes the CVV. In some instances, the CVV can be delivered to the user by other methods, such as short message service (SMS) or via a mobile application.

In order to comply with Payment Card Industry (PCI) regulations, typically merchants, issuers and processors, who handle card holder data (card number, CVV, expiry date), are required to meet a strict set of standards. In many instances the merchants, issuers and processors prefer to avoid the burden of PCI compliance, by working with partners who handle the raw card numbers and translate them to tokens instead.

SUMMARY OF THE INVENTION

The present invention allows card issuers/program managers to greatly increase security and eliminate online fraud while staying fully compliant with PCI without the burden of card PAN storage. The invention also protects the card issuer/program manager against CVV compromise at any other source—the user, the merchant, and/or the card issuer processor (the card processor associated with the card issuer/program manager). Further the invention also ensures that all online card transactions using CVVs are 2-factor authenticated, providing the additional benefits of verification offered by 3D secure without an actual extra redirect step.

The present invention is directed to methods and systems for payment card transactions, where a Card Verification Value (CVV) or Card Verification Code (CVC) is generated dynamically as part of a session.

The present invention is also directed to cards which lack a physical CVV located on the card itself, but rather, the CVV is created dynamically or on the fly, typically via an application. This reduces online fraud risk. As a result, even if the user loses his card, it cannot be used on-line by anyone.

Embodiments of the invention are directed to methods and systems for dynamically presenting the CVV to the user (requestor) (the terms “user” and “requestor” are used interchangeably herein, to indicate an entity, with the use of “user” and/or “requestor” depending on the stage of the process of the invention in which the entity is participating) within their phone application (app) and not on the card. The CVV does not exist until the user opens an application (app) on their trusted device, such as a smart phone, and prepares his account for a card transaction. At that point, a session is created for the user, the CVV is generated for any cards owned by the user where such cards are identified by their tokens. The CVV is available in the memory of the system of the card issuer/program manager, and is presented to the user (e.g., trusted device associated with the user) via a secure session within the application (app). This temporary CVV is short lived and only valid for the session duration. The method is Payment Card Industry (PCI) compliant, as the authorizing system, i.e., card issuer/program manager, does not have the card PAN, and the PAN is translated into a card token by another system such as with a third party processor. The card issuer/program manager is the authorizing system, and authorizes the transaction on the basis of the card token and the dynamic CVV.

The present invention allows card issuers/program managers to greatly increase security and eliminate online fraud while staying fully compliant with PCI, by utilizing a verification service, which may be independent, to verify the transaction without the burden of card PAN storage or handling on the verification service. The invention also protects the card issuer/program manager against CVV compromise at any other source—the user, the merchant, and/or the card issuer processor (the card processor associated with the card issuer/program manager). Further the invention also ensures that all online card transactions using CVVs are two (2)-factor (or 2-factor) authenticated (identified), providing the additional benefits of verification offered by 3D secure without an actual extra redirect step. The verification service, which may be independent, includes, but is not limited to a provider of an Access Control Server (ACS), which serves as a substitute for conventional 3D Secure verification such as by a one-time password sent to the phone (since the dynamically generated security code is already a one-time password, but procured pre-transaction).

The present invention is directed to methods and systems for payment card transactions, where a Card Verification Value (CVV) or Card Verification Code (CVC) is generated dynamically as part of a session relating to cardholders whose cards may be identified using tokenization.

Other embodiments of the invention include a bank or issuer provided mobile application, such as an online banking application where the CVV is made available to the user for all cards held by the cardholder (user), which are enrolled into the dynamic verification system.

Embodiments of the invention include a CVV generator application provided by a verification provider, where a user, after registration of his phone number with the verification provider, enrolls a number of participating cards into the application. The enrolment process involves confirmation with the card issuer and card issuer processor of the user's identity, which is identified by the phone number and the user's card number, which is identified by its token. Such enrolment is, for example, at the user request, or via some pre-invitation steps from the card issuer processor. Upon enrolment, the CVV is generated via the application (app) for such users would supersede the CVV on the back of the cards, and authorization requests for card transactions for such cards, would be routed via the system. For example, a user, George, could enroll into the CVV generator app his HSBC card xxxx-xxxx-xxxx-5434 and his Lloyds card xxxx-xxxx-xxxx-5232, where HSBC bank and Lloyds Bank are integrated into the verification network. After enrolment, for online transactions, the CVV on the card, is superseded by the CVV in the app, and during transaction authorization, the verification is performed by the verification system, which is implemented at, for example, HSBC bank, or, 1) its card issuer processor, or 2) its Access Control Server provider (e.g., CVV Verification Provider).

Embodiments of the invention provide a system, which is such that prior to generating the CVV, the user is first requested to confirm the specific amount or a range of amounts for which they are looking to do their next transaction, and the generated CVV is tied to the specific amount or range of amounts. Accordingly, should the CVV be correct, but the transaction amount out of range, the transaction will still be declined.

Embodiments of the invention provide a system, which is such that prior to generating the CVV, the user is first requested to confirm some information about the merchant they will pay the transaction at, and the generated CVV is tied to the specific merchant. Accordingly, should the CVV be correct, but the transaction requested by a different merchant, the transaction will still be declined.

Embodiments of the invention provide a system, which is deployed as multiple components where the verification component, which compares the currently valid CVV against the supplied CVV, is separate and outside the system of the card issuer (program manager).

Embodiments of the invention are directed to a method for processing a payment made by a payment card (e.g., debit, credit or other transaction card). The method comprises: receiving, from a device associated with a requestor (also known as a user), a request for a security code for at least one payment card assigned a unique token and which is associated with the requestor; responding to the request for the security code by authenticating the requestor, and, allowing the requestor to perform transactions using the at least one payment card. The authenticating the requestor includes: accepting a first identifier for the device, and, accepting a second identifier associated with the requestor; and, upon the authenticating of the requestor being successful: 1) generating a security code for the at least one payment card which has been assigned a unique token, 2) opening a session for the generated security code, the session open for a time period in which the generated security code is valid, and, 3) providing the generated security code to the requestor. Transaction data is received for a transaction using the at least one payment card, the transaction data including payment card information and a security code for the at least one payment card. It is then determined whether the payment card information corresponds to a payment card assigned to a unique token; and, if there is a correspondence (for example, matches), verifying the transaction for the at least one payment card, by comparing the received security code for the at least one payment card against the generated security code for the at least one payment card, provided the session for the generated security code is open.

The present invention is directed to methods and systems for payment card transactions, where a Card Verification Value (CVV) or Card Verification Code (CVC) (the terms “CVV” and “CVC” used interchangeably herein) is generated dynamically and valid for a short duration, for example, a session which is open, and therefore valid, for a predetermined time period, using a unique token instead of the card number for card verification, and utilizing multi-factor authentication to create a short duration session that governs the validity of the CVV/CVC associated with the card tokens.

The present invention is directed to methods and systems for card transactions, where the card need not be present to perform the transaction, e.g., payment, also known as a “card not present” transaction or payment. The disclosed methods and systems provide a dynamic CVV, as a security code. Implementations of the invention provide all the benefits of two factor based strong authentication/3D secure, in a manner where no one party including the issuer has access to the card, and the CVV, at any single time, post transaction.

The disclosed methods and systems dynamically generate a CVV and verify a transaction, such that when there is a valid session for a user (requestor) (the terms “user” and “requestor” are used interchangeably herein, to indicate an entity, with the use of “user” and/or “requestor” depending on the stage of the process of the invention in which the entity is participating), who possesses a card identified by its token, a dynamic CVV is generated, which can be used to verify the token of a card. This enables CVV verification on the card without any single party in the transaction processing chain other than the user, not even the verifying issuer, actually possessing all the details required to complete a transaction. These details include, for example, the card PAN and CVV and card expiry date. Additionally, not only is the CVV dynamic, but it is linked to the login session, which makes the CVV nonexistent when a session does not exist, which negates brute force attacks.

Also, the underlying session for the user can only be created on the basis of two factor verification of a user using a supporting identity: using a PIN (what they know) and a trusted device (what they have) where trust is established for a device by additionally verifying the identity of the user during the first session with a new non-trusted device. The additional verification could be done such as by verifying current access to the primary phone number linked to the user by sending a one-time password to the user. Successful verification results in linking the device as a trusted device for the user, the device being identified by a persistent device identifier which could be a hard to counterfeit hardware attribute of the device, or a server generated hard to guess unique fingerprint which is provided to the device after verification. Suitable trusted devices include, smartphones or mobile computers, mobile devices and other devices suitable for running client applications.

The present invention provides methods and systems that generate a CVV, i.e., a security code, with the generated CVV linked to a session and a card token. The CVV does not exist when the user is not logged-in to a session, and the card token or token, is linked to the CVV when the user is logged in to the session. The CVV is not directly linked to the card number or PAN.

The methods and systems of the present invention require that: 1) the user (represented such as by their phone number), must be logged in into a session to generate the CVV; and, 2) the system of login is based on a trusted device (phone) and a secret PIN or other personal identity, such as a touch identification (ID), e.g., fingerprint which is known/possessed by the user.

For example, should an imposter attempt to generate the CVV for a user, then the imposter needs to be able to get the user's trusted phone (or to know the unique secret device identifier assigned to the user's trusted phone by the server to impersonate the user's phone) and then to login using the user's identifier (phone number) and the user's PIN. Alternately, the imposter needs access to the user's sim card and their PIN in order to be able to login like that of the user on a new phone. Accordingly, the CVV is tied to the login, which is tied to a trusted device.

Reference is now made to FIG. 2A, which shows an exemplary operating environment, including a network 50, to which is linked a home server (HS) 200, also known as a main server. The home server 200 also defines a system, either alone or with other, computers, including servers, components, and applications, e.g., client applications, associated with either the home server 200, as detailed below. The home server 200 and its system belong or are associated with, for example, to a card issuer/program manager, which manages cards for financial transactions, such as credit cards, debit cards and other types of payment cards (collectively referred to as “cards” in this document). The home server 200 includes components, which form a system (or a portion of a system) for issuing tokens corresponding to cards, issuing CVVs (security codes) and controlling timing of sessions in which CVVs are valid, linking tokens to CVVs and performing matching of tokens for cards which the card issuer/program manager has issued, databases and other storage media for storing CVVs, tokens, card numbers, for example, as masked data, and processors (including, for example, hardware processors) for controlling the aforementioned. The home server 200 and system perform additional functions detailed below.

The network 50 is, for example, a communications network, such as a Local Area Network (LAN), or a Wide Area Network (WAN), including public networks such as the Internet. The network 50 is either a single network or a combination of networks and/or multiple networks, including also (in addition to the aforementioned communications networks such as the Internet), for example, cellular networks. “Linked” as used herein includes both wired or wireless links, either direct or indirect, and placing the computers, including, servers, components and the like, in electronic and/or data communications with each other.

The other servers linked to the network 50 include, for example, an application server 202, a card issuer/processor server 206, a card provider server 208, a server 210, representative of a merchant, and a server 210 of a merchant acquirer 212, the merchant acquirer for processing the merchant's card transactions. A user (requestor) 240 links to the network 50 via his trusted device, such as a smartphone 242, via a cellular tower 244. The user 240 also holds the card 20 of the present invention, of which an example card operation is detailed in FIGS. 3A-3D below.

This application server 202 stores and makes accessible, to devices, computers and the like, via the network 50, for example, by downloading, an application (APP) 203 of the present invention. This application (APP) 203, when installed and running on a trusted device, such as the smartphone 242 of the user 240, maps to the home server 200. The application 203 as installed on a device, e.g., smartphone 242, is discussed in operation below.

A server 206 belongs to or is associated with the Card Issuer Processor (for example, Global Processing Services FZLLC of Dubai UAE (GPS)), an entity who processes card transactions for the card issuer/program manager. This server 206 is linked to the network 50. This server 206 performs operations for receiving and processing various card data, including CVV's and card PANs, along with other data, creating and augmenting tokens, as well as performing other operations detailed below. This server 206 also includes, for example, databases and other storage media for cards and their PANs.

Server 208 belongs to or is associated with a card provider. An example card provider is MASTERCARD®. The server 208, for example, for MASTERCARD®, the card provider, is associated with a BIN (bank identification number), for example, the BIN of MASTERCARD®.

The server 210 represents servers of merchants, for example, ARGOS® (Argos Ltd. of Milton Keynes UK, www.argos.co.uk). Server 212 is the Merchant Acquirer's server, which processes card payment transactions for the merchant. The server 212 is, for example, the merchant acquirer, WorldPay (Payment Processing Services www.worldpay.com).

The user 240 is in possession of his trusted device 242, i.e., his smartphone, and card 20. The card 20 is shown in FIGS. 2B-1 and 2B-2. In addition to the PAN (including the BIN) and expiration date on the front side 20 a of the card 20, on the rear side 20 b, there is not a conventional CVV number. Rather, there is the word “APP” 25 in place of the CVV, or alternately, the CVV is not present on the card 20. The card 20 is, for example, a payment card, and may be a credit or debit card.

Attention is now directed to FIGS. 3A-3D, collectively known as FIG. 3, which show a flow diagram detailing computer-implemented processes in accordance with embodiments of the disclosed subject matter. Reference is also made to elements shown in FIGS. 2A, 2B-1 and 2B-2. The process and subprocesses of FIGS. 3A-3D are computerized processes performed by the system. The aforementioned processes and sub-processes are, for example, performed automatically and in real time. However, the processes can be permed manually as well and in combination with automatic processes.

In FIGS. 3A-3D and in the description of these figures below, the various parties associated with the transaction are indicated based on the server of FIG. 2A represented and/or associated with that particular entity. For example, the entity card issuer/program manager, represented and/or associated with the home server 200, is indicated as CARD ISSUER/PROGRAM MANAGER 200. Similarly, the entity card issuer processor, represented and/or associated with the server 206, is indicated as CARD ISSUER PROCESSOR 206. The entity card provider, represented and/or associated with the server 208, is indicated as CARD PROVIDER 208. The entity merchant, represented and/or associated with the server 210, is indicated as MERCHANT 210, and the entity merchant acquirer, represented and/or associated with the server 212, is indicated as MERCHANT ACQUIRER 212.

Prior to the START block 302 of the process detailed in FIG. 3, the application 203 has been obtained, e.g., by downloading from the application server 202, over the network 50, and installed by the user 240 on his trusted device, i.e., smartphone 242.

At the START block 302, tokens (also known as unique tokens, as each token is unique for a single issued card) are created and assigned for the card upon its issuance at the CARD ISSUER PROCESSOR 206 and shared with the CARD ISSUER/PROGRAM MANAGER 200. The process moves to block 304, where the CARD ISSUER/PROGRAM MANAGER 200 receives, from a user 240, also known as a requestor (e.g., a trusted device associated with the requestor): 1) a PIN (Personal Identification; 2) a login request, and, 3) a request for a CVV, from the device 242 (e.g., trusted device) of the requestor 240.

The process moves to block 306, where the user (requestor) 240 is attempting to log-in from a trusted device 242 (based on a unique secret device identifier) and with a user/requestor identifier, such as a PIN or other personal Identification or other identifier, such as a Touch ID (e.g., a fingerprint), which is known/available only to the user. For example, the trusted device 242 is from a list of trusted devices associated with each requestor. Should the log-in be accepted, the requestor (user) and the trusted device are acknowledged (by the CARD ISSUER/PROGRAM MANAGER 200), and the requestor (user) is logged in. This is a two factor identification, as the trusted device is identified, for example, via the unique secret device identifier, the first factor, and, the requestor (user) is identified via a user/requestor identifier such as the PIN, the second factor.

Also, should the first identifier of the two factor identification (authentication) for the trusted device represent a device which is not currently a trusted device (e.g., from a list of trusted devices associated with the requestor) for the requestor (user), this triggers a process of establishing trust in a new device to render the new device as the trusted device. This process includes, for example, confirming the current access to an identification method associated with the owner of the payment card(s), including a phone number associated with an account for the payment card(s).

For example, the user (requestor) 240 attempts to log in using their phone number such as “+447624222721” and their PIN “3234” from device 242. The unique secret device identifier (e.g., a long string value “asddad1314553636363663” which uniquely identifies the device 242) is automatically submitted to the CARD ISSUER/PROGRAM MANAGER 200 with the login request. The CARD ISSUER/PROGRAM MANAGER 200 checks whether “asddad1314553636363663” matches the currently valid trusted device identifier for the user represented by phone number “+447624222721”. Further the CARD ISSUER/PROGRAM MANAGER 200 also checks whether the PIN “3234” (entered by the user (requestor) 240) matches the PIN for the user represented by phone number “+447624222721”. If the PIN is valid but the device 242 (represented by unique secret device identifier “asddad1314553636363663”) is not trusted, a onetime password is sent (for example, by the CARD ISSUER/PROGRAM MANAGER 200), for example, by short message service (SMS) to the user's (requestor's) 240 phone number+447624222721. Providing the one time password results in the current device 242 (identified by secret identifier “asddad1314553636363663”) becoming the trusted device for user 240. If the device is a trusted device and the PIN is valid, the login is successful and a session is generated.

With the user (requestor) log-in verified and approved (authenticated), a user log-in session (for the authenticated user/requestor) is established (e.g., opened), the session being open and valid for a time period, as set by the CARD ISSUER/PROGRAM MANAGER 200. For any card the user possesses (including all cards possessed by the user/requestor), and which is identified by a linked or otherwise assigned token (unique token), a CVV (e.g., as a security code) is generated which is valid for the duration of the session. The opening of the session and the generation of the security code are performed contemporaneous in time, and may be performed in any order or simultaneously. The session may be, for example, of a fixed time, a random time within a time range. Further, a session is closed when a new session is opened such as by a new login, resulting in the generation of a new security code (CVV/CVC) for the same card(s), e.g., payment card(s).

The process moves to block 308, where the user is provided card selections of his cards from the CARD ISSUER/PROGRAM MANAGER 200, and the user selections for the card(s) are received, for example, by the CARD ISSUER/PROGRAM MANAGER 200. At block 310, the generated CVV(s) (as security code(s)) is/are transmitted to the user device 242 (e.g., from the server 200 to the client (device) 242) for each selected card (one or more cards of a user/requestor, including all of the cards for the user/requestor) together with a masked card number, for example, 5434-xxxx-xxxx-9456, and card expiry date.

Moving to block 312, the user 240, via the device 242 makes a card 20 purchase from a MERCHANT 210, for example, ARGOS®. The purchase includes the user 240 transmitting to, and the MERCHANT 210 receiving transaction data including at least: 1) the card PAN, 2) the CVV, and 3) the card expiry (expiration) date. The process moves to block 314, where the MERCHANT 210 transmits the transaction data including, for example, 1) the card PAN, 2) the CVV, and 3) the card expiry (expiration) date, to the MERCHANT ACQUIRER 212, for example, WorldPay Secure Payment Processing (WorldPay Group PLC of London UK, www.worldpay.com), who, for example, may work with ARGOS® to process ARGOS's card transactions.

The process moves to block 316, where the MERCHANT ACQUIRER 212 analyzes the BIN (Bank Identification Number) of the card PAN and recognizes the CARD PROVIDER. The MERCHANT ACQUIRER 212 transmits the transaction data, for example, the Card PAN, CVV, and card expiry date, to the CARD PROVIDER server 208, i.e., MASTERCARD®, associated with the BIN. The process moves to block 318, where the CARD PROVIDER 208 recognizes the card BIN and transmits the transaction data, e.g., the Card PAN, CVV and card expiry date, to ISSUER PROCESSOR 206.

At block 320, the ISSUER PROCESSOR 206 receives card PAN, CVV and card expiry date, and checks the card PAN against its active card set (stored, for example in a database or other storage media including cloud storage). If the card PAN exists in the active card set, the ISSUE PROCESSOR 206: 1) obtains the token representing the card, and 2) transmits the token and the CVV to the verifying system, for example, the CARD ISSUER/PROGRAM MANAGER 200.

The process moves to block 322, where the CARD ISSUER/PROGRAM MANAGER 200 receives the token and the CVV from the ISSUER PROCESSOR 206.

Moving to block 324, the first of a series of checks (e.g., comparisons) is now made by the CARD ISSUER/PROGRAM MANAGER 200. Here, it is determined whether the user (requestor) associated with the token is logged in to an open session. If an open session does not exist (a “no” at block 324), the process moves to block 330, where the transaction is not verified and is not approved. From block 330, the process moves to block 332, where the information is sent to the MERCHANT 210, who declines the transaction, and the process ends at block 338.

If yes at block 324, the process moves to block 326, where it is determined whether the provided (received) CVV matches the CVV (generated) for the token (i.e., the token/unique token assigned to the card/payment card), for the session active at this time. If no at block 326, the process moves to block 330 and subsequently blocks 332 and 338 as detailed above. If yes at block 326, the process moves to block 328, where additional checks are made.

These additional checks at block 328 include, for example, one or more of balance availability, card limits checks, fraud rules, and the like. However, these additional checks are optional, such that block 328 does not need to be part of the process. Should any of the additional checks not be passed, the process moves to block 330 and subsequently blocks 332 and 338 as detailed above. Should all additional checks be passed, the process moves to block 334, where the transaction is verified and approved.

From block 334, the process moves to block 336, where the information of the accepted transaction is sent to the MERCHANT 210, who completes the transaction. The process moves to block 338, where it ends.

The processes of blocks 324, 326 and 328 are shown in an exemplary order only. The processes of these blocks may be performed in any order, as these processes are performed, for example, contemporaneous in time, and may be performed simultaneously.

Also, should block 328 not be performed, as it is optional, if yes at block 326 (or block 324 if the order of blocks 324 and 326 was reversed), the process would move to block 334, where the transaction is verified and approved (and then to blocks 336 and 338 as detailed above).

Reference is now made to FIGS. 4 and 5A-5D, which show another embodiment of the invention in an exemplary operating environment (FIG. 4), and an example process (FIGS. 5A-5D) performed in this environment. This embodiment is similar to that shown in FIG. 2A (where similar elements are numbered identically or similarly and are in accordance with their descriptions above), but is different, in that a separate CVV Verification Provider (represented by the server 400, and referred to hereinafter as CVV Verification Provider 400) is linked to the network(s) 50. The CVV verification provider 400 is a separate entity, for example, not controlled by or related to any of the other entities of FIG. 4, all of which are described in FIG. 2A above, except where indicated.

Additionally, in the environment of FIG. 4, there are, for example, multiple home servers 200′, similar to the home server 200 for each Card Issuer/Program Manager, each home server 200′ representative of a Card issuer/Program Manager for each card of the user 240, represented by a token. (A single home server 200′ may be for multiple cards of the user, provided the cards are controlled by that Card issuer/Program Manager, e.g., two VISA cards from Wells Fargo® Bank). The Card Issue Processors 206′, are similar to Card Issuer Processors 206, but server 206′ represents multiple servers for multiple Card Issue Processors, and the server 208′ is similar to the server 208, but represents multiple servers for multiple card providers, e.g., MASTERCARD, VISA, DISCOVER, AMERICAN EXPRESS, DINERS, etc., as a typical user 240 has multiple cards, each represented by a token, from multiple different issuers 200′. The Card Issuer/Program Managers 200′, application server 202, Card Issuer Processors 206′, Card Providers 208′ and CVV Verification Provider 400, for example, form a dynamic verification system.

FIGS. 5A-5D show an example process performed in the environment of FIG. 4. This process is directed to an outside CVV verification provider 400 and its operation, and that the user 240 has one or more cards, and when the user 240 has more than one card, the cards may be from different card issuers/program mangers 200′.

In FIGS. 5A-5D and in the description of these figures below, the various parties associated with the transaction are indicated based on the server of FIG. 4 represented and/or associated with that particular entity. For example, the entity card issuer/program manager, represented and/or associated with the home server(s) 200′, is indicated as CARD ISSUERS/PROGRAM MANAGERS 200′, and may be a separate entity for each card issued, so that there may be multiple CARD ISSUERS/PROGRAM MANAGERS. The CARD ISSUERS/PROGRAM MANAGERS 200′ may be, for example, banks, such as Bank of America®, Wells Fargo®, Lloyds®, HSBC®, and the like. Similarly, the entity card issuer processors, represented and/or associated with the server 206′, is indicated as CARD ISSUER PROCESSORS 206′, and may be, for example, Global Processing Services (GPS), banks which do their own card processing, and the like. The entity card providers, represented and/or associated with the server 208′, is indicated as CARD PROVIDERS 208′ (e.g., MasterCard®, Visa®, Discover®, American Express®, Diners®). The entity merchant, represented and/or associated with the server 210, is indicated as MERCHANT 210, and the entity merchant acquirer, represented and/or associated with the server 212, is indicated as MERCHANT ACQUIRER 212. The entity CVV Verification Provider represented and/or associated with the server 400, is indicated as CVV VERIFICATION PROVIDER 400.

Prior to the START block 502 of the process detailed in FIG. 5A, the application (APP) 203 has been obtained, e.g., by downloading from the application server 202, over the network 50, and installed by the user 240 on his trusted device, i.e., smartphone 242.

At the START block 502, a token (also known as unique tokens, as each token is unique for a single issued card) is created and assigned for each the card upon its issuance at the respective CARD ISSUER PROCESSOR 206′ and shared with the CVV VERIFICATION PROVIDER 400. Each token is enrolled with the application server 202 together with an identity (e.g., phone number for the user 240 who owns the card. Optionally, the enrollment may be a selection of a secret PIN/Biometric and further verification of the identity of the user, such as by sending a one-time password from the respective CARD ISSUER/PROGRAM MANAGER 200′ to the user 240, to verify the identity and enroll the user into the dynamic verification system.

The process moves to block 504, where the CARD ISSUER/PROGRAM MANAGER 200, (or by its delegation, the Application server 202) associated with the specific card of the user 240, receives, from the user 240, also known as a requestor (e.g., a trusted device associated with the requestor): 1) a PIN (Personal Identification; 2) a login request, and, 3) a request for a CVV for each card owned by the user 240, from the device 242 (e.g., trusted device) of the user/requestor 240.

The process moves to block 506, where the user (requestor) 240 is attempting to log-in from a trusted device 242 (based on a unique secret device identifier) and with a user/requestor identifier, such as a PIN or other personal Identification or other identifier, such as a Touch ID (e.g., a fingerprint), which is known/available only to the user. For example, the trusted device 242 is from a list of trusted devices associated with each requestor. Should the log-in be accepted, the requestor (user) and the trusted device are acknowledged (by the CARD ISSUER/PROGRAM MANAGER 200′), and the requestor (user) is logged in. This is a two (2) factor identification, as the trusted device is identified, for example, via the unique secret device identifier, the first factor, and, the requestor (user) is identified via a user/requestor identifier such as the PIN, the second factor.

Also, should the first identifier of the two factor identification for the trusted device represent a device which is not currently a trusted device (e.g., from a list of trusted devices associated with the requestor) for the requestor (user), this triggers a process of establishing trust in a new device to render the new device as the trusted device. This process includes, for example, confirming the current access to an identification method associated with the owner of the payment card(s), including a phone number associated with an account for the payment card(s).

A User Log-in Session is now established which is valid for a time period. For any card the user owns, and which is identified by a unique token, having been issued for the card, a CVV is generated by a CVV Generating Entity, for example: 1) a CARD ISSUER/PROGRAM MANAGER 200′, 2) a CARD ISSUER PROCESSOR 206′, or 3) the CVV VERIFICATION PROVIDER 400. The CVV (which was generated) is valid for the duration of the session. The masked card number, for example, 5434-xxxx-xxxx-9456, and card expiry date, is transmitted, for example, from the CARD ISSUER/PROGRAM MANAGER 200′ (or by its delegation, the application server 202), to the logged-in user device 242.

The process moves to block 508, where the user is provided card selections of its cards from each CARD ISSUER/PROGRAM MANAGER 200′ (or by its delegation, the application server 202), for each card owned by the user 240, and the user selections for the card(s) are received, for example, by the respective CARD ISSUER/PROGRAM MANAGER 200′ (or by its delegation, the application server 202), which communicates data to the application server 202.

The process moves to block 509, where, for the selected cards represented by tokens, a request is received from the application server 202 for the appropriate CVV Generating Entity to provide a CVV to the user, and to provide the CVV to a verifying entity, for example, any one of: the CVV VERIFICATION PROVIDER 400, CARD ISSUER PROCESSOR 206′, CARD ISSUER/PROGRAM MANAGER 200′, application server 202, together with the validity period, and any additional verification rules.

At block 510, the generated CVV(s) (as security code(s)) for each selected card is/are provided to the user 240. For example, the generated CVV(s) are transmitted to the user device 242 (e.g., from the server 200′ to the client (device) 242) for each selected card (one or more cards of a user/requestor 240).

In an optional subprocess, after block 510, for example, the user may freeze their dynamically generated CVV (security code) for a certain point in time, to ensure that the card will work without interruption in situations: 1) where the user's device 242 does not have access to the Internet or other communications network to generate a new code, 2) the user 240 must provide details to a MERCHANT 210, who will charge the transaction at a later time to the generation of the CVV, and/or, 3) the MERCHANT 210 may charge the transaction at a later time to the generation of the CVV. In these situations, the user 240, via device 242, transmits a message to the server 200′, which ultimately notifies the CVV verification entity (listed above).

Moving to block 512, the user 240, via the device 242, makes a card 20 purchase from a MERCHANT 210, for example, ARGOS®. The purchase includes the user 240 transmitting to, and the MERCHANT 210 receiving transaction data including at least: 1) the card PAN, 2) the CVV, and 3) the card expiry (expiration) date (and typically the currency used for the purchase and the amount of the purchase). The process moves to block 514, where the MERCHANT 210 transmits the transaction data including, for example, 1) the card PAN, 2) the CVV, and 3) the card expiry (expiration) date, to the MERCHANT ACQUIRER 212, for example, WorldPay Secure Payment Processing (WorldPay Group PLC of London UK, www.worldpay.com), who, for example, may work with ARGOS® to process ARGOS's card transactions.

The process moves to block 516, where the MERCHANT ACQUIRER 212 analyzes the BIN (Bank Identification Number) of the card PAN and recognizes the CARD PROVIDER 208′. The MERCHANT ACQUIRER 212 transmits the transaction data, for example, the Card PAN, CVV, and card expiry date, to the corresponding CARD PROVIDER server 208′, for the card being used in the transaction, i.e., MASTERCARD®, associated with the BIN. The process moves to block 518, where the CARD PROVIDER 208′ (for the card used for the transaction) recognizes the card BIN and transmits the transaction data, e.g., the Card PAN, CVV and card expiry date, to ISSUER PROCESSOR 206′, for the card being used for the transaction.

At block 520, the CARD ISSUER PROCESSOR 206′ receives the card PAN, CVV and card expiry date, and checks the card PAN against its active card set (stored, for example in a database or other storage media including cloud storage). If the card PAN exists in the active card set, the CARD ISSUE PROCESSOR 206′: 1) obtains the token representing the card, and 2) transmits the token and the CVV to the verifying system (detailed above), for example, the CVV VERIFICATION PROVIDER 400.

The process moves to block 522, where the CVV VERIFICATION PROVIDER 400 receives the token and CVV from the CARD ISSUER PROCESSOR 206′.

Moving to block 524, the first of a series of checks (e.g., comparisons) is now made by the CVV VERIFICATION PROVIDER 400. Here, it is determined whether the user (requestor) associated with the token is logged in to an open session. If an open session does not exist (a “no” at block 524), the process moves to block 530, where the transaction is not verified and is not approved. From block 530, the process moves to block 532, where the information is sent to the MERCHANT 210, who declines the transaction, and the process ends at block 538.

If yes at block 524, the process moves to block 526, where it is determined whether the provided (received) CVV matches the CVV (generated) for the token (i.e., the token/unique token assigned to the card/payment card), for the session active at this time. If no at block 526, the process moves to block 530 and subsequently blocks 532 and 538 as detailed above. If yes at block 526, the process moves to block 528, where additional checks are made.

These additional checks at block 528 include, for example, one or more of balance availability, card limits checks, fraud rules, additional rules that could tie the CVV to a specific amount/range of amounts selected by the user, or that could tie the CVV to a specific payee, and the like. However, these additional checks are optional, such that block 528 does not need to be part of the process. Should any of the additional checks not be passed, the process moves to block 530 and subsequently blocks 532 and 538 as detailed above. Should all additional checks be passed, the process moves to block 534, where the transaction is verified and approved.

From block 534, the process moves to block 535, where the CVV VERIFICATION PROVIDER 400 provides a response to the CARD ISSUER PROCESSOR 206′, for the card of the transaction, who sends an authorization response to the MERCHANT 210. The process then moves to block 536, where the information of the accepted transaction is received by the MERCHANT 210, who completes the transaction. The process moves to block 538, where it ends.

The processes of blocks 524, 526 and 528 are shown in an exemplary order only. The processes of these blocks may be performed in any order, as these processes are performed, for example, contemporaneous in time, and may be performed simultaneously.

Also, should block 528 not be performed, as it is optional, if yes at block 526 (or block 524 if the order of blocks 524 and 526 was reversed), the process would move to block 534, where the transaction is verified and approved (and then to blocks 535, 536 and 538 as detailed above).

Optionally, the dynamic verification system is such that prior to generating the CVV, the user is first requested to confirm the specific amount or a range of amounts for which they are looking to do their next transaction, and the generated CVV is tied to the specific amount or range of amounts. Accordingly, should the CVV be correct, but the transaction amount is out of range, the transaction will still be declined.
